So to be clear you only need to cut through the stair landing to set the sleeve? What do you guys use to get through the metal/steel stair landing? Core drill bit.Yes but it's only a few inches of concrete and the metal pan. For poured concrete stairs we put sleeves in before the pour.
I mentioned the difference in post #7.In your experience of all the new building you worked in what % is the stair type of the pic you posted?
Yes, got it.I mentioned the difference in post #7.
A steel and Q deck building will almost always have metal stairways with concrete fill. A poured concrete building will use formed and poured conrete stairways. I'm guessing that maybe someone makes pre-fab versions but I have never seen them.
